    * Now let's draw some rectangles.

    *-----
    *    Notes about HSV color notation.
    * Imagine hue is a "rainbow" of colors, from 0.0 to 1.0.
    * 0.0 is red, then you progress to orange, yellow, green, blue, purple, and
    *  then back to red again.  (Not like a real rainbow.)  1.0 is red also.
    * HSV colors are easy for HUMANS, while RGB colors are easy for COMPUTERS.
    * Quick, what is the RGB for Pink?  Brown?
    * In HSV, you would think Pink is a low-saturation red at full brightness,
    *  thus you could say H=0.0, S=0.5, B=1.0; and that's off the top of my head.
    * Brown is a low brightness Orange, so H=0.0888, S=1.0, B=0.6; right out of thin air.
    * Need a highly contrasting color?  Easy in HSV coordinates.
    * Just pick the opposite hue, maybe maximize saturation (opposite of other color),
    *  and maybe also a min or max brightness.  Can't easily come up with highly
    *  contrasting colors in RGB coordinates in RGB space.
    * Need to "soften" colors?  Take each HSV coordinate, and lower the saturation
    *  by 10 %.
    * Need to "darken" colors?  Lower the brightness of each pixel by 10 %.
    *-----
    
    * Let's vary the hue and saturation, while keeping the brightness constant.
    * But you could vary any two parameters, while keeping the third constant.

***    Here is a very similar Visual FoxPro - Open Office example that..... 
***    1. Creates an OOo Calc spreadsheet 
***    2. Puts some strings into it. 
***    3. Puts some numbers into it. 
***    4. Puts some dates into it (as formulas) 
***    5. Saves it in Calc format (as C:\Example.sxw) 
***    6. Saves it in Excel format (as C:\Example.xls) 
***    7. Closes the document -- but this line is commented to leave the spreadsheet open in OOo
